The following oe* scripts exported to the path by oe-init-build-env do NOT provide any help option (either '-h' or '--help' or showing it after missing a required argument):
- oe-buildenv-internal
- oe-find-native-sysroot
- oe-git-proxy
- oe-gnome-terminal-phonehome
- oepydevshell-internal.py
- oe-setup-builddir
- oe-setup-rpmrepo
- oe-trim-schemas

The following scripts provide a help option and display help when executed without arguments:
- oe-check-sstate
- oe-pkgdata-util
- oe-publish-sdk
- oe-selftest
- oe-run-native (this displays an usage message when missing and argument)

On the following one all parameters are optional and help is displayed on demand:
- oe-build-perf-test


The behavior should be standard for all scripts we export to the path. According to this:
- It's necessary to add a help option for scripts in the first list and standardize it for 'oe-run-native'.
- Additionally, it's necessary to display help if a script is executed without any required arguments.
